Soft-bodied insects, earthworms and slugs are the primary food sources for the midland brown snake. Researchers have found that 75 percent of the midland brown snake diet consists of slugs.
Native to midwestern and southeastern states, the midland brown snake inhabits moist areas, such as marshes, ponds, gardens and vacant subdivision lots. Unlike other snakes that lay eggs, this species gives birth to live young measuring 3 inches long. The average adult length is 9 to 13 inches.
Midland brown snakes are completely harmless to humans as their only defense is flattening their heads and excreting fecal matter on their captors. Flower and food gardens benefit from their presence because they eat plant-damaging pests.
